Heat-shrinkable tubing is
universally applied for the insulation of connections or for the end-handling
of electric wire, for the insulation of soldered points on resistors and
capacitors, for the identification and encapsulation of electric wire, for the
corrosion-proofing of metallic rods or tubes and for the protection of
antennas. Heat-shrinkable tubes are used for the corrosion-proof and waterproof
connection of fibre optic cable.
